19、ar driven SSGD-250 Drawworks offers a design unique to the industry. By overpowering a drawworks with AC motors, we are able to create a single shaft, single speed drawworks with hoisting performance comparable to a conventional drawworks. The result is a simple design with few mechanical parts, a s

20、mall footprint and low weight. These drawworks require minimal maintenance, are entirely self-contained and completely enclosed.Features/BenefitsElectric Motors:The Drawworks is equipped with 1 ea. GEB-22A1 (General Electric) alternating current (AC) motors. The motors are Exe motors with forced air

21、-cooling. The motors have installed temperature sensors (PT100 elements) in the stator windings and for monitoring the main bearings. Encoders are mounted at the motor non-drive end for measuring the motor speed. The speed feedback from the encoder gives input to the frequency converters for optimal

22、 regulation of the AC-motor parameters.Motor Cooling Blowers:Blower skid assembly is provided for cooling of the Drawworks motors and ventilation of the enclosures. The skid consists of two blowers, back draft dampers, high efficiency weather louvers and an outlet plenum chamber.A damper is provided

23、 on the Drawworks roof between the plenum chamber and the AC-motors for isolation of the motors.Drawworks Control System:The Drawworks Control System consists of the following main parts: Drawworks Control cabinet Miscellaneous Field Instrumentation Drawworks Interface Panel Emergency stopSafety:The

24、 SSGD-500 Drawworks Control System is designed to provide enhanced safety and integrity for the operation, machinery, and the personnel on the rig. This is achieved by an active control philosophy with equipment self-checks and monitoring, and by use of duplicated critical equipment.The primary safe

25、ty requirement for the SSGD-Drawworks is that one single point of failure shall not cause any hazardous condition leading to either personnel injury or any damage to the equipment.The SSGD Drawworks is designed as a lifting device for drilling operations with fail-safe spring applied brakes.Specific

28、n diameter and has Lebus grooving for 1-3/8 wireline. The drum is shaft mounted between spherical roller bearings that are bolted to the drawworks frame. The drum is direct driven through a single gear reduction of 10.5 to 1 ratio. Pinions are mounted directly to the motor shaft to reduce the overal

29、l size and weight of the gear set. The AC drilling motors are directly coupled to the main drum shaft, providing continuous operation without the use of transmissions or clutches.Service/Dynamic Braking:Normal service braking is performed by the AC motors by generating power into braking resistors. The motors and frequency drives are capable of holding full load at zero speed indefinitely. Load speed is limited by the control system to stay wit
